What should you know about chest tightness during sleep?

Lying down can allow stomach acid to move upwards, causing burning, cough or pressure. Asthma may cause night-time wheeze, cough or a tight feeling, while nasal congestion and airway irritation can make breathing feel harder. Panic symptoms may wake someone suddenly with a racing heart and fear. Angina can also occur at rest. None of these possibilities can be confirmed from timing alone.

Record when you wake, your position, meals before bed, wheeze, cough and whether symptoms settle after sitting up. Avoid smoke and keep prescribed medicines available as directed. If reflux symptoms are suspected, discuss meal timing and treatment with a clinician rather than relying on repeated self-treatment. Arrange a review when episodes recur or disturb sleep.

Get emergency help if tightness is severe or does not settle, or if it comes with major breathlessness, fainting, blue lips, sweating, confusion, or pain spreading to the arm, jaw or back. Seek prompt assessment if you are repeatedly woken, need to sit upright to breathe, or symptoms follow exertion.

Ask whether you need assessment for asthma, reflux or heart-related causes, and whether breathing tests or medication changes are appropriate. Bring a sleep and symptom record, including snoring, cough, wheeze and bedtime meals.
